Manual Verification
Once a full instrument calibration is in place it is not always necessary to repeat the
full calibration procedure when the instrument is next used. Instead a calibration
verification can be performed. (There is no benefit in verifying each calibration
individually, re-calibration is just as quick.)
If a scanning acquisition is to be made and the calibration is to be checked:
Set up a scanning acquisition over the
required mass range and at the required
scan speed in the normal way.
Start the acquisition and inject the
reference solution so that reference data is
acquired.
Stop the acquisition.
Access the calibrate dialog box and set all
peak matching parameters to the same
values that were used for the calibration.
Select
Process
,
Verification from file... and check
Scanning Calibration
(see below).
Select Scanning Calibration and either MS1 or MS2 depending on the type of
data acquired.
Clicking on
Browse...
, select the acquired file and enter the start and end scans
of the reference data.
Select
OK
to verify the calibration.
